Abstract (en)
[origin: US2014295285A1] The present invention refers to a method of preparing a separator, comprising: producing a dispersion comprising inorganic particles, a polymer binder, polymer fibers and a solvent; applying the dispersion on the top surface of a substrate to form a non-woven fabric web as a layer comprising the inorganic particles, the polymer binder and the polymer fiber, in which the inorganic particles are positioned in gaps of the polymer fibers and adhered thereto by the polymer binder; and drying and compressing the non-woven fabric web to obtain a non-woven fabric substrate; a separator prepared by the method; and an electrochemical device comprising the separator.
